Serial No. 801,995.

The invention to be hereinafter described relates to a traversable suction roll for paper making .machines. p Inpaper makin machines the making wires must be perio 'cally renewed, as is well understood. This requires time and labor and means hea tion of the mac ine during the period over which it must be shut down for the change. Many wire changing mechanisms have been devised in as many attempts to solve the problem. The present invention, however, attacks the difiiculty from a different angle.

In the present case, the suction rollitself, is

slid laterally through and out of the frame,-

the looped wire dro ped vertically into line with the free end 0 the roll and the roll returned. The job is then completed In order to more clearly disclose the construction, operation, and use of the invention,

a In. the present instance, the invention has been shown as applied to a paper making machine in which the making wires travel (in a generally vertical-direction or plane in contradis'tinction to the regular standard Fourdrinier in which the wire travels in a generally horizontal direction or plane. Such vertical arrangement is set forth in detail'in my yfiiiendin'g application Serial Number 29,600

ed May 11, 1925, to which reference may be had for such'features which, ,however, as to expense in the lost pro'duc-- details, form no part of the .present invention. In the particular application of the invention illustrated, a transfer suction roll is used in the invention. The suction rolls on which the web is formed-the forming rolls-ware not provided, in the machinev shown with the invention.

Referring to the drawings in detail 1 indicates a forming roll about which a making wire 2 passes. In the particular instance shown, there are two forming rolls and wires, the two wires slightly converging to the lower end, with suitable tension rolls for each wire. In the lower end of one wire is a guide roll 3. In the lower end of the other wire is a suction transfer roll 4 which acts, also, as a lower guide roll for that wire. As will be seen in reference to Fig. 1, the rolls 3 and 4 are so positioned in their respectiwe wires that the two wires run together or in travelling contact for a short distance around the first part of thearc of contact or engagement between the suction transfer roll and its wire. In that .part of the arc is placed the suction box or chamber which simultaneously bonds the two webs and transfers one from its wire to the wire of the-transfer roll. A second suction of the invention.

The present invention has to do particulated cooperating parts in relation to the removal and replacement of the making wire.

To that end,'Figs. 2v to 5 disclose the details ofconstruction on an enlarged scale. Referring to these figures in detail,"-the suction transfer r0114 has a considerably extended head'for its rear end, one ort-ion extending much further into the sheil'end than in the usual standard roll, for a urpose to be later disclosed, while the remainder pro'ects con-- siderably farther outwardly beyon the shell and to provide ample room for two considerably spaced parallel bearings 7 and '8 between which issecuredthe regular standard driving Iarly with suction transfer roll 4 and its rerolls in general use. The construction of the suction roll itself, except as to the head at the rear end is well known and need'not be given here. At the, opposite end the usual head and hearing are provided and the usual removable or loose piece 10. At the rear end, the two spaced bearings 7 and 8 are securely fixed on a carriage, the bearing 8 being provided with a foot plate 8' by which that bearing may rest upon and be secured. to

V the machine framesee Figs. 2 and 5. Suitable bolts or other connecting means may be used for this purpose, as will be readily understood. Incidentally, itmight be mentioned, that the roll is shown in its opera tive position in Figs. 2 and 5.

p The carriage 11, on which bearings 7 and 8 are mounted, is of inverted U shape in lateralcross section and extends the full length of the two bearings and intervening space. It is supported by and upon parallel, spaced, oppositelydirected channel beams 12. The beams 12 are mounted on a common lateral pivot providing a, vertical rocking movement at'that end. As shown in the drawings it is a well known form of rocker pivot. The'opposite ends which extend inwardly beneath the bearings 7 and 8, when the roll is in operative'position, are adjustably supported on a small cross rod or lateral bar 14 seated in a suitable yoke 15 on the upper end of a suitable screw-jack. Obviously other elevating means may be used, that shown being merely one well known type. Thus, it will be seen that raising rod 14 will raise the inner end of the beams 12, swinging them on pivot 13. Necessarily, the carriage 11, bearings 7 and 8 and roll 4 will be moved. To provide anti-friction, free-running engagement between the carriage and supporting beams, trolley wheels or rollers 16 are provided, one pair for each beam. They are mounted in any suitable and well known manner on the inner faces of the vertical carriage members in position to engage the horizontal members of the channel beams, while, at the same time, having their inner ends slightly spaced from the. vertical walls of the channel beams, all as clearly shown in Fig. 4. Note should be made that the rollers are so disposed that when the beams are in a true horizontal position. the rollers or trolleys do not actually engage the horizontal or tread members of the channel beams. Instead, there is just avery slight space between. Thus when the connecting bolts have been removed from the foot-piece 8' and the jack is operated, on the first slight upward movement, the roll, with its carriage will be rocked vertically upward about its 1 front end, to just about the same extent that the beams will be rocked vertically about their rear ends. The movement, in both cases, is extremely slight, as will be understood. This movement takes up the very slight distance or space between the rollers and their respective treads or channel beam flanges. bringing each in engagement with its respective trea as will be clear. At the same time, it raises the weight of the roll from the loose piece 10. The beams thus slightly raised are on a very minor incline outwardly toward the rear pivot point 13.

In this position, the roll is readily started and easily run out on its beams. When out, the

loop of the new wire is simply let down vertically through the frame into line with the suction roll end and the roll run back through the loop, its free end positioned to rest on the loose piece and the' jack lowered to its initial position. i

carriage, when the rollxis in operative position, a pedestal 17 is provided. It acts, really, as a separate frame member in sustaining the weight of the roll. It is positioned close to the frame, directly beneath that end of the carriage which supports the rear bearing 7, when the roll is in operative position. It has a relatively wide base and substantially inverted U shaped upper. end, the upper end being so proportioned and disposed as to fit between the beams 12 and seat the corresponding end of the carriage 11, at the instant that the roll reaches horizontal or operative position. On slight further downward swing of the beams, their horizontal flanges will disengage the rollers 16 and, at the same time, the beam ends will engage and rest upon a horizontal web 18 of the machine frame, so that the weight of the beams will be off, of the jack and supported on the web and pivot at opposite ends, respectively, as will be clear. Likewise, it is obvious'that, when in operative position, the entire. weight of the roll and carriage is firmly supported by the machine frame, including the pedestal 17,'no part of it being sustained by the beams 12.

As will be noticed in reference to Fig. 1 the wire as it passes from roll 4 to roll ,5 is deflected toward 4 by 5. In other words, roll 5 in its operative position would be in the path of the lower end of the new wire when that wire is dropped into position to receive the roll 4. To avoid this, the bearings of roll 5 are bolted or'otherwise secured to blocks 18 slidably mounted on suitable ways on the machine frame and operable toward and from the roll 4 by hand screws '19 or the like threaded through a frame member andinto the respective block. So, when a wire is renewed, the roll 5 may be easily and quickly slid out of the path of the wire oop. 1

Of course the wire must be placed within the machine frame and assed over the forming roll before it is let own so that its lower loop may receive the roll 4. For this pur- As an adequate support for the bearing ently of the rest of the machine.

pose, the upper portion of the frame is provided with a member 19 pivoted at one end and detachably bolted at the opposite end. When the wire is to be renewed,.the-vat is drained, decklcs moved back, and front end bearing of the forming roll removed, all as will be readily understood. Then the tensioning rolls are taken out and the member 19 swung outwardly on its pivot. Next the roll 4 is run out on beams 12 and roll 5 drawn out of the path of the wire. With the parts in these positions the new wire is passed into the frame, over the forming-roll and dropped down so that its lower loop is in position to receive the free end of roll 4. The various parts are then all returned to their respective operative positions, as will be readily understood.

In the machine selected for illustration, a pair of converging wires has been shown. It is evident thata single wire or a greater number than two wires may be used and that they may be variously disposed otherwise than as shown. It will also be evident that the invention may be applied to other types of machines than the one shown and to various other machines with their making Wires arranged and running differently than in the single instance shown. Many changesmay be made in the construction, arrangement, and disposition of the several parts of the invention without departing from the field thereof and, within the scope of the appended claims, it is meant to include all such within this application.
